Ariel is no doubt correct that Selenium Dioxide will raise the pamor on your blade. It won't give you the correct traditional coloring that arsenic will render. So in the end it all depends on your preferences and how authentic you want your blade to look in the end.

... it doesn't work!

I already tried it and yes, I can get a very nice black blade but no pamor visible. I also tried different concentrations but still the results are quite dissapointing. I also tried Nital and Ferric Chloride that I normally use for etching wootz blades, but with pathetic results. So, what works for etching wootz or blacking steel, apparently doesn't work for revealing the pamor... or at least I didn't know how to make it work.

PS: Selenium dioxide in diluted form works also fine for revealing the watering pattern of wootz.

That's interesting! How much do you dilute it?

I started from Perma Blue which is based on Selenium Dioxide and Nitric acid, which I already had diluted to about 20%. (At this concentration I etched an Indian Katar that I didn't manage to etch with the classic Nital and Ferric Chloride (even this concentration blackened the Katar completely but upon gentle wiping with Pre-lim, I got a very nice an visible watering wootz structure).) Then I diluted this even more to about 10%, but I only got a nice and uniform grey patina that didn't reveal the pamor even after selective cleaning with Pre-lim.

PS: I used undiluted Perma Blue for blacking an antique Japanese Tsuba with stellar results, and that's how I had it on hand to experiment with the Wedhung.
